Imagine two completely unrelated businesses, A and B, both have toll free phone numbers (so both incur cost for a call to their phone number) but the numbers are close enough for wrong dialling to occur.
Both companies are not huge, but A has a larger customer base than B.
The numbers are correctly advertised with no mistakes.
Would A have any liability to B for a significant volume of misdialled calls, resulting in a significant expense to B? Would A have to adjust their number on the request of B?
